e1cefd0654 fix(subagent): orchestration fix-wave G — configurable timeouts/caps, honest child outcomes, fenced timeline writes (#2937)
Four verified-open issues in the subagent-orchestration family, one PR:

- #1594: dream synthesize subagent job/wait timeouts promoted from
  hardcoded 30/35-min constants to config keys
  dream.synthesize.subagent_timeout_ms / subagent_wait_timeout_ms.
  Approach ported from stale PR #1596 (credit @ai920wisco).
- #2778: add_timeline_entry joins the subagent brain-tool allowlist,
  fenced fail-closed by the shared enforceSubagentSlugFence (extracted
  from put_page's inline check — same trusted-workspace allow-list /
  wiki/agents/<id>/ namespace policy). The per-turn output cap is now
  resolveMaxOutputTokens (data.max_tokens → agent.max_output_tokens →
  8192, was hardcoded 4096); a max_tokens stop surfaces as
  stop_reason 'max_tokens' instead of a silent end_turn, and a
  mid-tool-round cap hit injects a truncation note so the model
  re-issues the dropped call.
- #2782: patterns phase status now reflects the child outcome —
  non-complete outcome with zero writes → fail (PATTERNS_CHILD_<OUTCOME>),
  partial writes → warn. Patterns timeouts get the same config-key pair
  (dream.patterns.subagent_timeout_ms / subagent_wait_timeout_ms).
- #2113: facts extraction cap is config facts.extraction_max_tokens
  (default 4000, was hardcoded 1500); stopReason 'length' is checked,
  retried once at 2x the cap, and surfaced on stderr instead of
  silently extracting zero facts.
